Erdath's surface, with an average temperature just two degrees above freezing, is dominated by fjords, tundras, ragged mountains, and vast ice fields covering much of the seas. Due to Erdath's size, the planet has a highly active plate tectonics system, with plates smashing into each other and later pulling apart at such momentums as to push up vast mountains even under the planet's higher gravity. Over Erdath's five billion year history, most of the planet's land area has thus been affected, creating a very mountainous surface.

Erdath's surface is dominated by a single large supercontinent, Drovala, with the rest of the planet's land area broken up into a large number of subcontinents and island arcs. The poles are largely iced over, with permanent ice caps forming over 14% of the planet.

Erdath is the third planet of the Holias System in the Vernarca Nebula, of the Ervo Sector of the Silky Way galaxy. It is a temperate, if cool, world with life covering much of its surface. In the distant past, it was little more than a colony of the robotic Edrons before their destruction in war, but today it serves as the homeworld of the Lrenn, capital of the Erdathian Federal Republic, and a major world of the Vernarcan Federation.

Erdath was named so by the ancient Lrenn, after the god of the dust then believed to rule all. Its surface is teeming with life of all sizes, from bacteria to great whales, from the depths of the ocean to the most dizzying of mountain peaks. As the homeworld of the Lrenn, it has served a vitally important role in the history of the Vernarcan Federation, and indeed was the sole founding member to remain out of the hands of the Alliance of Five during the War of the Broken Bow.

Geography

Erdath's surface, with an average temperature just two degrees above freezing, is dominated by fjords, tundras, ragged mountains, and vast ice fields covering much of the seas. Due to Erdath's size, the planet has a highly active plate tectonics system, with plates smashing into each other and later pulling apart at such momentums as to push up vast mountains even under the planet's higher gravity. Over Erdath's five billion year history, most of the planet's land area has thus been affected, creating a very mountainous surface.

Erdath's surface is dominated by a single large supercontinent, Drovala, with the rest of the planet's land area broken up into a large number of subcontinents and island arcs. The poles are largely iced over, with permanent ice caps forming over 14% of the planet.
